## Summary

CB-Cwr is a diverging colormap from the colorcet collection. Inspect its perceptual lightness, chroma, and hue profile on colorcurio.us.

## Perceptual profile (OKLCh)

- Lightness: 0.773 → 0.797 (range 0.203, min 0.773, max 0.975); non-monotonic; midpoint 0.975
- Chroma: min 0.001, max 0.129, mean 0.060
- Hue: 213.9° → 28.1° (span 174.4°), path monotonic-cw; quadrants: azure, red
- Endpoint temperature: cool → warm
- Perceptual ΔE: total 60.7, mean/step 0.238, max step 0.463, smoothness 0.704, speed 0.238

## Colorblind safety (ΔE under simulated CVD)

- Protanopia: ΔE total 40.3; preserves order: yes
- Deuteranopia: ΔE total 46.7; preserves order: yes
- Tritanopia: ΔE total 67.3; preserves order: yes
